The "rule of thumb" is that the lower the paraffin melting point is the higher the compression rate is.
It would be nice to ask the manufacturer why the change; perhaps they have added something that reduces the melting point, but I really do not think they should do that without warning the users.

Subject: [Histonet] Paraplast Xtra Melting Point?


Happy Friday to all!  For those of you who use Paraplast Xtra, had you noticed that the melting point printed on the bag has changed from 56 degrees to 52 degrees?  I've seen several comments recently about problems with compression with this paraffin; and we have been experiencing the same problem.  A friend and former coworker contacted me about similar problems they are having in her new lab, and they had noticed the change in the melting point.  We get our Paraplast Xtra from Fisher, but it's difficult to say who is actually making it from the information on the bag.  Does anyone else have experiences to share?  I'm uncertain if this is the cause of our compression issues, but I'm throwing it out there for all of you experts.  Thank you in advance!
